Monaco JSON Viewer

Makes JSON easy to read. Open source. Built on top of the very familiar Monaco editor, same as the one being used in VS Code.

Auto-detects JSON when you load it in a browser tab.

Features: Syncs theme automatically with browser theme Syntax highlighting Bracket pairing and color highlighting Collapsible trees, with indent guides Clickable Links Works on any valid JSON page – URL doesn't matter

Note: this extension might clash with other browser extensions that modify the DOM before it runs. If it doesn't seem to be working, try disabling other extensions. If it clashes with an extension you need, open an issue and I'll try to find a solution.
